Usage
Information
As soon as you apply a DCB policy with PFC enabled on an interface, DCBX starts exchanging 
information with PFC-enabled peers. The IEEE802.1Qbb, CEE, and CIN versions of PFC TLV are 
supported. DCBX also validates PFC configurations received in TLVs from peer devices.
By applying a DCB input policy with PFC enabled, you enable PFC operation on ingress port traffic. 
To achieve complete lossless handling of traffic, you must also enable PFC on all DCB egress ports or 
configure the dot1p priority-queue assignment of PFC priorities to lossless queues (see pfc no-drop 
queues).
To remove a DCB input policy, including the PFC configuration it contains, enter the no dcb-input 
policy-name
 command in interface configuration mode.
